valgrind complains open_file_or_dir() causes a memory leak.That is because
if we open a directoy by opendir(), and then we should call closedir()
to free memory.

We don't need callers to manage string storage for each pretty_sizes()
call. We can use a macro to have per-thread and per-call static storage
so that pretty_sizes() can be used as many times as needed in printf()
arguments without requiring a bunch of supporting variables.
This lets us have a natural interface at the cost of requiring __thread
and TLS from gcc and a small amount of static storage. This seems
better than the current code or doing something with illegible format
specifier macros.

For any btrfs-$FOO executable, rename the main source file from
$FOO.c to to btrfs-$FOO.c
This makes it slightly more obvious what's building what,
and allows us to write a default rule in the Makefile for
these tools.
(also add btrfs-calc-size to the list of objects to remove
on make clean)
